You might have figured this out already but just in case: I should have been a little more clear about the meaning of 'primary infection'. The first time you are infected is called a 'primary infection'. It is at this time that the IgM antibodies are created. After you recover from the first, 'primary' infection, your body will probably not make IgM antibodies again. IgM antibodies will linger for a while, but eventually, they will be removed from your blood and levels will drop below the 'reference' values.
When you have a 'reactivation' of a virus, more of the IgG antibodies will be created.
It's interesting to me that the EBV NA (Nuclear Antigen) IgG AB (antibody), and EBV VCA (Viral Capsid Antigen) IgG levels get so high. I have a suspicion that the high levels of these antibodies actually interfere with the body's ability to fight the virus. I wonder if they are an ineffective immune response that interferes with other, more effective antibodies by blocking them. If so, it would explain why medications such as Rituximab are effective. Rituximab rids the blood of antibodies.
Prolonged fasts will also lower antibody levels in the blood. I once tried a multi-day fast but felt so unwell after the second day that I gave up. I'll have to try it again and see how I feel afterward.
